I have available 2 B 145's. B on front and No 44 /# on rear. See next picture for rear view. These two beauties compliment each other wonderfully along with other pieces you may have . The crisp Blue colour with a few bubbles and an offset pin threading. The Green one is crisp and clean that is highlighted by much threading of Amber throughout the insulator. Both insulators are free of any damage. I'm asking US $20. Plus shipping. PayPal cheque or MO. Thanks. Graham.
